the meeting edges of the sheet or sheets ofmetal forming each section, and the production of an enduring leak-'tight seam has been either unsatisfactory or costly.

The present invention rovides a radiator l5 simulating the shape an form of the usual househeating radiator, which, being formed of drawn'or extruded shells, or of tubes with an end or end seams, or a seam running transversely thereof, and which in thin gauge metal and without long straight or substantially straight seams', avoids the objection to seams encountered in radiators formed of light gauge sheet metal.

The invention further provides a novel method 'of forming the radiators.

A number of embodiments of the invention are illustrated in the accompanying drawings, in which- Fig. 1 1s a side elevation of a radiator ac- 80 cording to the first embodiment of'the in-v Y vention, with parts shown in section. v

. Fig shown in Fig. 1. fl Fig. 3 is an enlarged cross-section on` the 35 line 3 3 of Fig. 2.

Fig. 4 is a view, in elevation, of` a shell from which the sections of theradiator areformed.. Y

Fig. 5 is a view, similar to Fig. 1, of .a

second embodiment of the invention.

. 6 and 7 are elevational views of one' v formed and then flattened.

. 2 is an end elevation of the radiator the shell' 13 illustrated in Fig. 4 of the drawing. 'The shells .constituting the sections 11 are preferably flattened as indicated at 15, a round shell such vas 134 being first The sections 11 are preferably assembled in such manner that the flat faces of adjoining sections face one another. c

The plurality of sections 11 are connected for intercommunication, and also for Jrigidity, at top or bottom, and preferably at both 615"V top and bottom, as indicated at 20, 21.

The connecting means. 20, 21 are conveniently short tubes or nipples 23, 24, oppositely threaded, and fitting openings 27, 28 in the sections 1l. y

. As the walls of the sections l1 ma be, and preferably are, of a light gauge, iiaving a thickness corresponding to about 20, B. & S. gauge or lighter, for example, the openings 27, 28 are conveniently bushed or rimmed withrings 30, which are seamed or crimped upon the edges ofv the metal around said openings 27 28, and threads are provided in these rings 30 for engaging thethreads on the nipples 23, 24.

The sections 1l are preferably embossed adjacent the openings 27, .28, as indicated at 33, to stiien the sections at these points, and also to provide space between the ni ples corresponding to the thickness of e sections. l

The sections 11 are also preferably corrugated lengthwise, 'as indicated at 35, Figs.

2 and 3. These corrugations lserve to strengthen the sections, and also provide constrictions`37 lengthwise of the sections, forming channels 38 between the constrictions, to facilitate the flow or circulation of the heating Huid. y A The open end 40 of the tube is closed in suitable manner.' The end is preferably -flatf tened so that the edge portions lie together, and the'length ofthe edges being short it is neither diiicult nor expensive to close the ends by practically any usual means. The referred means is a. strip of relatively eavy metal`42 (Figs. 1 and 2), which is seamed or crimped on the end 40. Such a joint will be` durable, and not affected by strains, shocks, etc., to which the radiator 10| may be subjected, to the same extent as lon seams, as for example hose in sheet me radiators.

Referring now particularly to Figs. 5 to `9, inclusive, of the drawings, the numeral another.

The plurality of sections 51 are connected for intercommunication, at top or bottom,

4being hereshown as connected to al base or manifoldl 57, and as being in communication with 'one another through themanifold and the open end of each shell or section, as indicated at 59. Y

The vopen ends of the sections or shells 51 may be connected to the base o'r manifold 57 in any vsuitable manner. Preferably the) open ends of lthe shells have a neck 60 of reduced diameter, which neck 4has a flange 62 thereon, adapted to be pressed against a neck 64 formed upon the base or manifold 57. The {iange 62 is conveniently pressed against said neck 64 by a coupling' or collar 66 having threaded .connection with said neck 64, .asindicated at 68.' The manifold or'base 57 is formed with a plurality of these threaded necks 64 toprovide for the connection of the several sections making up the radiator. The means of connection described provide aconvenient means for connecting the sections lto the base where the space between the sections is less than the width of the section. Any other means of connecting the sections to the base or manifold may be used which is suitableto any particular arrangement of :the sections with relation to the manifold, which may be chosen. f

The sections are also preferably connected for rigidity, .as for example, by means of a strapy or straps 7(1), 71, passin around the series of sections, as illustrate in Fig. 5.

Where the Walls of the sections 55 are of light gauge metal, having a thickness corresponding to about 20, B. & S. gauge, for example, the iange 62 is a practical means o'duniting the sections to the base or mani- The sections 55'are preferably corrugated lengthwise, as indicated at 75, Fig'. 6, similarly to the corrugations 35, Fig. 2. These corrugations serve to strengthen the sections and also provide constrictions lengthwise of the sections, forming channels between the. constrictions to facilitate the'flow or circulation of the heating liuid, 'as described inv reference to the embodiment illustrated in Fi s. 1 to 3, inclusive.

he sections 15 or 51, shownin Figs.v 1

od, the vsections or lshells 11 and ,M51 are 70 formed by drawing or extruding deep shells 13 open at one end, as-indicated at 40, Figs. 4 and 9. These shells are then fiattened as indicatedl in Figs. Sand 7 of the drawing.

The attened shells are then preferably '(6 corrugated or indented longitudinally, as indicated at 35 and 75, Figs. 2 and 6, the indentations or corrugations forming constrictions 37, between which constrictions 37 channels 38 are provided for the lcircu- 80 lation of the heating iuid.

The walls of the tube 13 are drawn quite thin, as for example toa thickness of No.

20B. & S. gauge or less.

A plurality of shells or sections'are asseln-y 3 5 bled into the form of a radiator, the interiors of the sections being in communication, as indicated in Figs. 1 and 5 of thel drawings.

According to one specific procedure, the

margins of the shell Vat the open end are pressed together, and closed in suitable manner, as by meansl of a strip of metal 42 which is crimped or seamed upon the edges of the section. Openings 27, 28 may be formed 95 in theupper or.lower portions of the shell, orl in the upper and lower portions ofthe shells, and one shell or section joined to another by a nipple or nipples threaded in said opening or openings.

According to another specic mode of procedure, the open end 40 of the shell 13 maybe reduced to form a neck 60, as indicated in Fig. 8. A flange 62 is preferably formed atv the outer end of the neck 60.

The sections with the necks 60 may be joined together to form a radiator, by connecting the sections through the necks 60 with a suitable base or manifold 57, Fig. 5. A threaded coupling or flanged collar 66 110 serves @to clamp the flange l62 against a part ofthe base or manifold 57.

The linventive ideas may receive other embodiments than those herein specifically illustrated and described, and the method 115' may be carried out by lother modes of procedure than those specically described.- l What is claimed is:l 1. A' metal radiator comprising sections composed of longitudinally-flattened shells 120 `of light gauge closed at. one end, said shells being seamless throughout.

2. A metal radiator comprising longitudinally flattened shells -of light gauge, said shells being closed at 'one end'and seamless 12,5

dinally-attened shells of light gauge, said' l shells each being closed at one end and seam- .together as not to be able to be turned, said less throughout, and having a neck of `reshells having reduced necks, a base or mani- `duced diameter provided with a clamping fold, and couplings on said necks connect- 10 ange at itsn open end. ingnsaid shells to said manifold.
